    pressure drop

    Demet Provide metal capacity required to

    reach run length; low HDS activity

    HDS activity

    Conversion Backbone for HDS/HDMCR/HDN;

    metals tolerant

    Deep

    Conversion

    Convert least reactive S/MCR to

    meet product target

    Design Activity For Each Layer

    Metal Capacity Fit for Purpose

    HDV activity higher towards reactor inlet to remove the

    metals in feed and protect subsequent layers

    HDS activity higher towards reactor outlet to tackle

    more difficult sulfur species in feed

    Metal capacity for each layer is designed to be

    sufficient for the run length
